I've been using MyBB for three years seeing as it's a free and open source forum software.

MyBB as usual. It's the best.

MyBB, Xenforo, IP.Bulletin, and vBulletin.
vBulletin being my first, MyBB second, IP.Bulletin third, and then Xenforo.

Mostly myBB, but atm I am creating my own website without any tools.

I've only ever used MyBB and it's all I plan on using.

I'm using MyBB. I'd never change.

I used vBulletin & MyBB. Both are pretty good forum software, but I prefer MyBB since its free. :3

I Personally, like Xenforo and Mybb because there just very fast.

Once i finish planning out my website I plan to use MyBB, then upgrade to XenForo or IPB

MyBB, big fan of it haha.
